摘要:

以福建三明金丝湾森林公园为对象,设置8个样地,以林分结构指标和景观因子为基础,耦合美景度对样地进行综合评价。进而基于生态风景林林分群落特征、林分结构及美学质量的作用,构建生态风景林目标树法优化经营措施,并实施、对比,以揭示耦合美景度的目标树优化经营的可行性。结果表明,优化后林分的混交度、角尺度、大小比变化分别为1.699%,-2.083%,-0.800%;Margalef丰富度指数、Simpson多样性指数、Pielou均匀度指数均有所增长,增长幅度分别为4.508%,2.841%,3.030%;优化后的林分美景度有较大改善,增加幅度为90.788%。基于目标树经营策略风景林林分结构调整技术使得林分结构得到进一步优化,在满足区位生态功能的生态需求基础上,能有效提高森林资源的景观美化价值,耦合美景度的生态风景林目标树优化措施可为生态风景林的林分优化提供可行方法。

Abstract:

The Jinsiwan Forest Park in Fujian Sanming is taken as the object and 8 sample plots are set up.In addition stand structure index and landscape factor before optimizing the management are taken as the variables,then the multiple linear regression model is built,a further target tree tending optimal management of ecological landscape forest is set up coupled with the scenic beauty estimation and implemented at the same time.Meanwhile,this paper discusses the effect of this method on the characteristics of the stand structure community,the stand structure and the aesthetic quality of the ecological landscape forest.And the results showed that compared with the data before adjustment,the mingling intensity,angular scale and size ratio of the stand structure were 1.699%,2.083% and 0.800% respectively;The Margalef richness index,Simpson diversity index and Pielou evenness index had increased and the growth rate was 4.508%,2.841% and 3.030% respectively. The optimized scenic beauty of the stand structure has been greatly improved,the increased rate is 90.788%. Based on the target tree management strategy,the adjustment technique of stand structure of landscape forest can satisfy the ecological requirement of ecological regional function,which makes the stand structure be further optimized,the species diversity be increased,and landscaping value of the forest resources be improved.Target tree tending optimal management of ecological landscape forest coupled with the scenic beauty estimation provides a feasible method for forest stand optimization of ecological scenic forest.

Key words: target tree tending, ecological landscape forest, optimal management strategy, scenic beauty estimation
